Firefox can no longer play Netflix movies. Firefox loads the Netflix site. Firefox attempts to play the movie. Then, Firefox can't play the movie. Netflix says "Your browser is no longer supported." This happens every time there is a Firefox update! Do you guys not test your products in development before release? Please fix your product. I tried all your 'help' items.

Browser Console XHR messages (toggle DRM off/on in Preferences) gave me a status '401 Unauthorized' error message, sometimes: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401

Make sure you have updated to Widevine 4.10.2209.1 and aren't using Widevine 4.10.1582.2 You may have to update to Firefox 78.11.0. Try to toggle DRM off/on to see if that makes Firefox (re)load DRM components.

Ur suggestion to get firefox to download upgraded version of Widevine did not work

I turned it on and off, and it loaded

Version 4.10.1582.2 Last Updated June 3, 2021

I got upgraded to 89.0 (32-bit) When the error occurd.

So atleast part of the error is that Widevine 4.10.2209.1 is missing x86 version atm?
